The effect of MgO diluents in combustion synthesis of $TiB_2$ nano particles was investigated. The reaction $TiO_2\;+\;B_2O_3\;+\;xMg\;{\rightarrow}\;TiB_2\;+\;5MgO$ was used to synthesize $TiB_2$ nano particles. The combustion velocity was measured to examine the relation between the reaction temperature and the morphologies of particles. The diluent MgO did not react with the reactants and played a role to decrease combustion temperature. As the MgO diluents contents increased, the particles with the smaller size and the narrower size distribution were synthesized. At the condition of 6 mole of MgO, the combustion wave velocity was about 5 cm/see and the synthesized particles showed the size of 60 nm with narrow size distribution.

Purpose : The purpose of this study was to examine the effects of PNF of irradiation using an indirect treatment of the stroke patient's static weight support and walking speed. Methods : Was carried out a total of nine different the PNF method of treatment for patients with left hemiplegia stroke. PNF of treatment is not in the non-paralyzed side of the trunk and upper and lower extremities by applying resistance and increased strength of the affected side. Assessment of treatment weight support both feet measured and modified using the timed up and go test were compared before and after treatment. Results : Treatment of the paralyzed side of the quadriceps and hamstring, gluteus medius muscle strength increased, and both sides of the foot body weight support improved walking speed was increased. Conclusion : Irradiation using PNF indirect treatment improves the function of the gait of stroke patients.

Purpose : This study was aimed to examine the Influence of PNF indirect treatment for frozen shoulder patient Methods : Frozen shoulder patient was measured range of motion test of shoulder joint, visual analog scale(VAS) for pain and clean up the mirror activity at pre intervention and post-intervention in 2 weeks. Results : The ROM, activities of shoulder were increased and decreased VAS point for pain after treatments. Conclusion : We found that PNF indirect treatment could improve ROM and functions of shoulder and pain for frozen shoulder patient.

Pupose : This study aimed to examine the Influence of stregthening for Transverse abdominis and resistive breathing exercise to use PNF on fulmonary functions and static sitting posture in adult stroke patient. Methods : Left hemi-plegic patient was masured pulmonary function test and analyzed sitting posture of alignment at pre intervention and post-intervention in 4weeks. Results : The pulmonary functions was increased and changed good alignment of trunk on sitting position after treatments. Conclusion : We were found that stregthening for Transverse abdominis and resistive breathing exercise to use PNF could improve pulmonary functions and sitting posture for stroke patient.

홈 네트워크 기술의 발달로 가전기기와 청보기기의 제어 및 관리를 위한 홈 네트워크 관리 기술에 대한 중요성이 확대되고 있다. 그러나 이러한 기기들은 서로 다른 인터페이스를 사용함으로서 상호간의 호환성이 결여되어 있다. 따라서 이를 쉽게 통합하여 관리할 수 있는 확장성 있는 관리 시스템이 요구되고 있다. JMX는 IT 자원과 관리 인터페이스 및 시스템 간의 독립된 계층을 기술한다. 이를 통해 관리 애플리케이션이 하위 관리 프로토콜과 무관하게 관리 데이터에 접근할 수 있도록 한다. 본 논문에서는 홈 네트워크 시스템을 통합 관리하기 위한 프레임워크를 설계하였고, 센서 네트워크 환경에서 JMX를 이용한 홈 게이트웨이를 구현하였다. 이러한 설계 및 구현을 통해 PDA 또는 원격 PC를 이용해 가정 내 정보기기들을 감시 및 관리할 수 있는 흠 네트워크 통합 관리 시스템을 구축하였다. With the progress of home network technologies, the importance of the home network management for control and management of the digital appliances is increasing. However, using different interfaces for these digital appliances is lack of compatibility between these systems. So we need some extensible managing system which integrates and manages these systems. The java management extensions(JMX) describes an isolation layer between an IT resource and an arbitrary set of management interfaces and systems. JMX provides accessible management data while simultaneously shielding the application from management protocols. In this paper, we designed frame work that integrates and manages home network system and also implemented home gateway using JMX on sensor network environment. Through this researches, we implemented the home network integrated managing system which can manage and monitor the home appliances with PDA or remote PC.

Purpose The purpose of this study was to investigate characteristics of the forced pulmonary function test effect by changes in lung function related to postures and by Transverse Abdominis(TrA). Contraction in standing position during forced inspiration and expiration with young female adults. Methods 10 young female adults were recruited this study. pulmonary Function test was measured with a Master-screen Body (VIASYS Inc., CA, 미국). To check the changes in lung function with different postures, we tested pulmonary function in the standing and supine position each. In the standing position, while the transversus abdominis was activating, we compared the forced inspiration with the forced expiration. Statistical analysis was used Independent t-test to know difference between forced inspiration and expiration of activated TrA. Results According to the study, the change of pulmonary function were statistically significant difference in the standing compared to the supine position. The contraction of the transversus abdominis causes decrease in the change of forced inspiration and increase in the change of forced expiration. Conclusion The se results indicate that spontaneous contraction of the TrA in standing position helps pulmonary function. And the selective contraction of the transversus abdominis at the end of forced inspiration makes increases in the forced expiration.
